Study on the relationship between internal pressure and expansion rate of hydraulic hose
Pages 378 - 384
Abstract
In the sealing performance test of the hydraulic hose, it is necessary to inject a certain pressure of gas into the hose and hold the pressure for a certain period of time, and judge whether there is a leak by the pressure difference between the two ends of the hose. Since the hose will expand under the action of the internal gas pressure, the outlet pressure will be lower than the inlet pressure, and it is impossible to directly determine whether the hose is leaking. In this paper, by establishing a hydraulic hose model with a diameter of 19mm, using finite element software to simulate the pressure holding process of the hose, observe the radial deformation and volume change of the hose in this state, and study the relationship between the expansion rate of the inner volume of the hose and the pressure in the tube. Using this relationship, the outlet pressure of the hose under a certain inlet pressure condition can be obtained, and the outlet pressure can be compared with the actual outlet pressure to judge whether the air tightness of the hose is good.
